The link you showed is kind of a modified version. It showed the back rounding. I do these with lighter weight on occasion for various reasons, however, in most cases, I would strongly advise doing them as you first desribed, i.e. breaking at the hip, sending the burtt way back, keeping the back flat, chest pufed out and shoulder bladespinched together to help keeping the back flat. This should keep the emphasis where you want it, on the hips and hams without endangering the spine. Just take care in not overloading so much your back does round.

The pain your experiencing may be related to a lack of lower back flexibility. However, you can lift a lot more weight safely if you keep your back straight, which will build your hamstrings more. Meanwhile, your erectors still get worked hard isometrically.
